Plethysmography is a widely used technique to assess breathing parameters in conscious and spontaneously breathing animals. Additional outcomes provide deeper insight into lung function, such as two validated indexes representative of airflow obstruction: EF50 (flow at mid-tidal expiratory volume) and sRaw (specific airway resistance) are derived. 

This document discusses:

  • Specific airway resistance (sRaw)
  • How sRaw is measured 
  • Mathematical and physiological description 
  • Advantages and limitations 
  • Review of applications and publicationsusing sRaw
